  • This is regarding Potassium Permanganate solution?

    I will be making up a Potassium Permanganate solution and leaving it for 5 days, to show the change in concentration of it. After those 5 days are over and I have to titrate it again (To show the change in concentration), do I shake it first before using it? Or do I just take it from the top of the container? As keeping in mind MnO2 will have formed.

    Any help would be appreciated (:
